In A Nutshell A 37-member international team produced the most precise direct measurement of the Hubble constant ever recorded, with just 1.1 percent uncertainty. By linking a dozen different cosmic ...

A spectacular cosmic event nicknamed “SN Winny” could help solve one of astronomy’s biggest mysteries: how fast the universe is expanding. This rare superluminous supernova, located 10 billion ...

Scientists have known for decades that the universe is expanding, but research in the past few years has shaken up calculations on the speed of growth -- raising tricky questions about theories of the ...

The most precise measurement yet shows the Universe is expanding faster than expected, deepening the Hubble tension. The ...

All the tools for measuring it in the local, recent Universe give fairly consistent results, around 72 to 74 kilometers per ...

A comprehensive new study combines decades of research to reveal that we're missing an essential component in our ...

For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right now? The expansion rate, called the Hubble constant, ought to come out the ...

Cosmologists have spent decades trying to pin down exactly how fast the universe is flying apart and whether that rate is ...

Recent surveys hint that the rate of cosmic expansion changes dramatically over time; if that's true, then the universe could ...

A new synthesis of astronomical measurements confirms a persistent mismatch that could point to physics beyond current models.

The universe is expanding faster than previously thought, according to a team of astronomers using the Hubble Telescope. How much faster? Five to nine percent faster. Initially the expansion of the ...

A major international study by astronomers has confirmed that galaxies near our Solar System appear to be moving away from us faster than expected. This recession speed is described by the Hubble ...
